soemtimes my headlights dont go on and i have to give i a little tap so they come on? what can be loose? can it be the connection to the bulbs are loose?

 

Where excatly are yo giving a "lil tap" at? That could give you an idea of where the short may be

 

just the front of the headlight

 

try your headlight plugs, then check the plug inside the steering column that connects to the signal arm (I had a problem there once myself) and then try the three boxes that are grounded (2 on battery side, one is the relays, another is a small plasic rectangular shape that has a ton of black wires coming out of it, and one of those on the other side as well) make sure those are grounded very well. (I had a problem with those once too)

 

yeah, i had the same problem. i couldn't find out what it was, but then i ended finally switching the bulb off another car, and it turned out being the bulb had a bad socket, even though i couldn't visibly see anything wrong.
